Elevated levels of mercury in fish caught and tested in Boyd and Carter lakes in Larimer County prompted consumption warnings Thursday from the state health department.

The fish testing is part an ongoing, five-year sampling plan of approximately 120 water bodies in the state by the Colorado Department of Public Health and Environment and the Colorado Division of Wildlife.

Of 50 water bodies where testing has taken place, 17 required consumption advisories.

After testing last month, consumption advisories were canceled for 16 water bodies.
